Figure 1 Distribution of baseline PP in CRT-D and LBBB patients. American Journal of Cardiology 2014 114, 1053-1058DOI: (10.1016/j.amjcard.2014.07.014) Copyright © 2014 Elsevier Inc. Terms and Conditions
Figure 2 Effects of CRT-D on echocardiographic measures in patients with high and low PP. ΔVolume/baseline = (1 year volume − baseline volume)/baseline volume. ΔSD/baseline = (1 year SD − baseline SD)/baseline SD. LVESV = left ventricular end-systolic volume; LVEDV = left ventricle end-diastolic; SD = standard deviation of dyssynchrony measure. The bars represent median values; p <0.05 for all 3 comparisons. American Journal of Cardiology 2014 114, 1053-1058DOI: (10.1016/j.amjcard.2014.07.014) Copyright © 2014 Elsevier Inc.
